SHEET-REGISTERING MECHANISM.

Specification of Letters Patent.

Patented Jan. 24, 1922.

To all whom it may concern:

Be it known that we, CARL E. CHRISTO- PHEL, a citizen of Germany, andFRED J. EISERMAN, a citizen of the United States, both residing at PearlRiver, in the county of 'Rockland and State of New York, have inventedcertain new and useful Improvements in Sheet-Registering Mechanism, ofwhich the following is a specification.

This invention relates more specifically to sheet registering devices inwhich the registry edge of a sheet is moved into engagement with aregistering surface and has for its primary objecttoprovide an improvedconstruction, combination and arrangement of parts whereby a moreperfect control of the sheets is secured. Particular objects ofinvention will appear in thespecification and be'pointed out intheclaims, reference being had to the accompanying drawings in which ourinvention is exemplifiedin a preferred embodiment. In the drawings,-

Figure 1'is a top plan view of this preferred embodiment; V

Figure 2 is a sideelevation of the same, parts being broken away andparts shown in section;

Figure 3 is a front elevation according to the line 33 of Figure 1,parts being shown in section;

Figure 4 is a section on the line 1-4, Figure 2, parts being broken awayand parts shown in elevation; and

Figure 5 is a section on the line 5-5, Figure 2, parts being broken awayand parts shown in section.

In the embodiment of our invention shown on the drawings, a supportingbar 1 is arranged to extend inthe direction in which thesheetis to beregistered. As shown, the device is employed for side registering asheet with respect to a side gage. Slidably mounted upon the bar 1 is anadjustable strap 2 which may be clamped to the bar 1 by means of a setscrew 3 operated on a gib 4 which is in engagement with the bar 1. Thestrap 2 is provided with a hub or boss 5 through which extends a screw 6which may be adjusted longitudinally by means of knurled nuts 7. Pinnedto a reduced end of the screw 6 is thehub or boss 8 of a bracket 9 whichis slidablymounted on the bar 1. The bracket 9 carries a depending arm10 which terminates in a base-platell, the upper'surface of saidbase-plate being disposed in substantiallv the plane of feed of thesheets which are to be registered. This base-plate is provided with agroove 12 within which is reciprocably mounted a slide 13, the uppersurface of said slide being in the same plane with the top surface ofthe base-plate 11. As shown best in Figures 1, 2 and 3, a cover 14 isarranged above the base-plate 11 andslide 13, said cover being providedwith an integral bearing lug 15 which is also integral with a lever arm16. Said cover 1 1 is provided with a slot 17 which approximatelyregisters with the groove 12. Agrub or set screw 18 is adapted to engagethe reduced end portion 19 of a stud within the bearing lug 15. Said endportion 19 of the stud is eccentric to a journal portion 20 of saidstud, which is provided with an enlarged head 21 for confining apressure roller 22 which is 'ournaled on the portion 20. It will be seenrom Figures 2 and 5 that by turning the stud in its bearing, thepressure roller 22 may be. raised or lowered with respect to the cover 11, the position of said cover being thereby varied with respect to thebase-plate and slide whenever the pressure roller 22 is bearingagainst'the slide 13 or upon a sheet covering said slide. A slideregister gage block 23 is arranged to determine the position of thelateral edge of the sheet for each registry movement. The lever arm 16is keyed to a rock shaft 24 to which is also keyed a cam arm 25. Saidcam arm 25 carries a cam roller 26 which travels over a profile cam 27having a rest portion 28' for holding the pressure roller 22 and cover14 in its extreme position away from the slide 13 and a rest portion 29which permits said roller and cover to lie in its extreme positionnearest to said slide. The rest or dwell portion 29 of the oscillatorycam is provided with an extended cam surface 29 which is adapted tomomentarily lift the pressure roller 22 at the inner extreme of theslides movement so that the effective action of said'slide upon a sheetdoes not begin until the slide has begun its outward movement. Theprofile cam 27 has a hub portion 30 which is journalled on a stub shaft31 which is secured by a set screw 31' within a bracket arm 51 of theslidable bracket 9. A miter gear 32 meshes with a second miter gear 33,the latter gear being s'plined to'an oscillatory shaft 34. As shown inFigure 2, the profile cam 27 is provided with an arcuate slot 35 andwith adjustable abutments 36 and 37 at op osite ends of said slot.Referring now to igure 4, a lever arm 38 which is rigid with the mitergear 32, has its bearing hub 39 freely journaled upon the shaft 31 andis provided with a laterally projecting boss 40 which carries a pin 41,said pin being disposed within the slot 35,01. the profile cam 27. Thelaterallydeflected end portion 42 of the lever arm 38 carries a pin 43upon which is journaled an anti-friction roller 44. This roller 44 isdisposed between spaced pins 45 (see Figure 5) which project upwardlyfrom the slide 13. It will be seen that by means of this construction,that a lost motion connection is provided between the slide oscillatinglever and the profile cam 27.

As shown in Figure 3, the bracket 9 is provided with a curved arm 46within which is reciprocably mounted the upper end of a spring rod 47Said spring rod carries near its lower end a flange or collar 48 betweenwhich and the arm .46 is disposed a compression spring 49. The lower endof the spring rod 47 is pivotally mounted on a pin 50 which projectslaterally from the lever arm 16. By this construction, yieldable meansare provided which tend to hold the cover in its lower extreme positionand at the same time press thecam roller 26 tov the profile cam 27.

From the foregoing description, it will be seen that the reciprocatoryslide and the pressure roller 22 are operated in positivelytimedrelations to each other. A lost motion connection of predeterminedamount which may bevaried at will to meet requirements, makes it,possible to secure any desired relation between the periodical rise andfall of the pressure roller and reciprocatory movement of the slide.
